A review of the measures of the stock of human capital used in empirical growth research reveals that human capital is mostly poorly proxied. The simple use of the most common proxy, average years of schooling of the working-age population, misspecifies the relationship between education and the...

This paper proposes a new method of calculating the proportion of permanently impoverished persons among persons in poverty as a whole. The paper shows that the widely used Shorrocks-Index for decomposing permanent and transitory inequality can also be acquired to describe poverty. This method...

As regards labor market effects of International Outsourcing, empirical studies have difficulties in confirming theoretical results. The use of different indices adds to the puzzle. The paper examines whether measurement differences are one reason for the mismatch between empirical and...

We extend the definition of a convex risk measure to a conditional framework where additional information is available. We characterize these risk measures through the associated acceptance sets and prove a representation result in terms of conditional expectations. As an example we consider the...

Comparing groups with respect to hypothetical constructs requires that the measurement models are equal across groups. Otherwise conclusions drawn from the observed indicators regarding differences at the latent level (mean differences, differences in the structural relations) might be severly...

The regional or national innovation performance has been repeatedly measured in the literature; but it has so far not been discussed what this means, especially in relation to a region. What is the contribution of a region to innovation output? The usual approaches implicitly assume that higher...

A service provider firm in an outsourcing relationship is distinct from a typical firm because it is not a stand alone organization and fits somewhere in between the value chain of its client's business. Thus, conventional factors like wages, capital, rent, energy consumption cannot...

History is replete with overt discrimination on the basis of race, gender, age, citizenship, ethnicity, marital status, academic performance, health status, volume of market transactions, religion, sexual orientation, etc. However, these forms of discrimination are not equally tolerable. For...

The availability of efficiency estimation software - freely distributed via the internet and relatively easy to use - recently inflated the number of corresponding applications. The resulting efficiency estimates are used without a critical assessment with respect to the literature on...
